Utilisation of a balloon-mounted coronary stent in the treatment of a patient with petrous carotid artery dissection.

A man in his 50s presented with acute left-sided weakness, facial drooping and slurred speech, suggestive of a major stroke. Imaging revealed a complete blockage in the right internal carotid artery (ICA) due to dissection. Perfusion studies showed a significant area at risk of infarction. Attempted navigation of standard carotid stents failed due to the tortuosity of the ICA. A balloon-mounted coronary stent was successfully deployed in the petrous ICA segment, restoring blood flow. A follow-up MRI confirmed stent patency, and the patient achieved complete recovery with return to baseline function. Symptomatic carotid artery dissections can be treated with stenting to prevent strokes, however, tortuous ICAs in distal dissections pose a technical challenge. Balloon-mounted coronary stents, though not approved for this use, can offer a feasible solution. This case highlights the need for further research and development of devices for managing dissections in distal locations in tortuous ICAs.
